Steel windows have become increasingly popular in South Africa for both residential and commercial applications. Their unique combination of strength, durability, and aesthetic appeal makes them an attractive option for homeowners and architects alike. This article will discuss the advantages of steel windows, the different types available, popular brands in South Africa, costs, maintenance tips, and how to find a reliable supplier.

Advantages of Steel Windows in South Africa

  • Durability: One of the primary benefits is their durability. Steel is a strong and resilient material that can withstand harsh weather conditions, making them perfect for South Africa’s varied climate. Unlike wooden or aluminum windows, steel windows are resistant to warping, rotting, and rust, ensuring a longer lifespan.
  • Security: They offer exceptional security. The robust material and secure locking mechanisms make it difficult for intruders to break in. Many homeowners in South Africa opt for them to protect their families and properties from theft and vandalism.
  • Aesthetics: Distinctive industrial appearance that can add character and charm to any building. With a variety of styles and finishes available, these windows can complement both traditional and modern architecture. The slim profiles also allow for larger expanses of glass, providing unobstructed views and increased natural light.
  • Energy Efficiency: Steel window frames can be designed with energy-efficient glazing, which helps to minimize heat loss in the winter and keep your home cool during the hot South African summers. This not only reduces your energy consumption but also lowers your monthly utility bills.

Types of Steel Windows in South Africa

There are several types of steel windows available in South Africa to cater to various design preferences and functional requirements. Some of the most popular types include:

1. Fixed Windows

Fixed steel window frames are non-opening and are used primarily for decorative purposes or to provide natural light. These windows are ideal for rooms where ventilation is not a priority or where other windows provide sufficient airflow.

2. Casement Windows

Casement steel window frames are hinged on one side and open outward using a crank or lever. These windows offer excellent ventilation and are easy to clean, making them a popular choice for homeowners.

3. Sliding Windows

Sliding steel window frames glide horizontally on tracks, providing a space-saving solution for rooms with limited space. They are also ideal for creating a seamless connection between indoor and outdoor living areas.

4. Awning Windows

Awning steel window frames are hinged at the top and open outward from the bottom, providing ventilation while protecting the interior from rain. This type of window is commonly used in bathrooms and kitchens, where increased airflow is essential.

5. Tilt and Turn Windows

Tilt-and-turn steel window frames combine the features of casement and awning windows, allowing the window to either tilt inward from the top or swing open like a casement window. This versatile design provides excellent ventilation options and makes cleaning the exterior of the window easier.

6. Double-Hung Windows

Double-hung steel window frames have two vertically sliding sashes, allowing both the top and bottom sashes to open for ventilation. This classic design is often found in traditional homes and offers a timeless aesthetic.

7. Single-Hung Windows

Similar to double-hung windows, single-hung steel window frames have two sashes, but only the bottom sash can be opened for ventilation. This type of window is often more affordable than its double-hung counterpart.

Popular Brands in South Africa

Several well-known brands manufacture them in South Africa, including Wispeco, Metal Windows, and Steel Window Services. These companies offer a range of steel window frame products to cater to different budgets and design preferences.

Prices are also subject to change over time, so it’s crucial to contact suppliers for the most up-to-date information. However, to provide a rough estimate, the following are some common steel window sizes and their approximate price ranges in South Africa:

Steel Windows – Maintenance Tips

They require minimal maintenance to keep them looking their best and functioning smoothly. Here are some tips for maintaining them:

  1. Regularly clean the windows using a soft cloth and a mild detergent solution to remove dirt, grime, and fingerprints.
  2. Inspect the window frames and seals for signs of damage or wear and address any issues promptly.
  3. Lubricate the moving parts, such as hinges and locks, with a suitable lubricant to ensure smooth operation.
  4. If your steel window frames have a painted finish, touch up any scratches or chips to prevent rust from forming.

Finding a Reliable Steel Windows Supplier

When selecting a steel window frame supplier in South Africa, it’s essential to do your research and consider the following factors:

  1. Reputation: Look for a supplier with a solid reputation and positive customer reviews.
  2. Experience: Choose a company with a proven track record and experience in the industry.
  3. Range of products: Select a supplier offering a variety of types and designs to suit your preferences and budget.
  4. After-sales support: A reliable supplier should provide ongoing support and assistance with any issues that may arise after the installation.

Steel Windows vs. Other Window Materials

They have several advantages over other window materials, such as aluminum and wood. As mentioned earlier, they are highly durable, secure, and energy-efficient. They also have a unique aesthetic appeal that can enhance the appearance of any building. However, they can be more expensive upfront and may not be suitable for all budgets or design preferences.

Aluminum windows are lightweight and low maintenance, but they may not offer the same level of security or durability. Wooden windows, on the other hand, provide a classic and warm appearance but require regular maintenance to prevent rot and warping.


Steel windows are an excellent choice for homeowners in South Africa seeking a durable, secure, and attractive window option. With various types, styles, and brands available, there is a steel window solution to suit every need and preference. By following the maintenance tips and choosing a reliable supplier, you can enjoy the benefits of steel windows for years to come.
